To alt whom t may concern.'

Be it known that we, Louis A. KEENE and Mori' R. PHARIS, citizens of theUnited States, residing, respectively, at Waterman, in the county ofDekalb and State of Illinois, and Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inManure- Spreaders, of which the following is a specilication.

The invention refers to manure spreaders,

and one of its objects is to enable the oper-` ments are equallysusceptible of use in con-` nection with manure spreaders of otherconstructions. No limitation therefore is intended by the reference toour patents above noted.

In the accompanying drawings, Figure 1 is a perspective view showing themechanism for operating the apron-traveling means and thespreader-cylinder-rotating means. Fig.

2 is a detail view showing in side elevation the operating lever fordisengaging, changing, and rengaging the gear which actuates theapron-traveling mechanism, also the means for locking said lever in anoperative position. Fig. 3 is a side elevation showing the mechanismforl transmitting power from the traction wheels to thecylinder-rotating mechanism, and also the device for disengaging theclutch. Fig. 4 is a top plan view of the same. Fig. 5 is a detail viewof the cam wing shown in Fig. 3.

The manure spreader disclosed in the aforesaid patents comprises avehicle in the form of a wagon, t-he bottom of the wagon box being madeup of an apron mounted upon a series of rollers at each side of said boxand along the middle line thereof, and being thus adapted to be movedlongitudinally of the wagon box. The rear end of the wagon box isoccupied by a spreader cylinder mounted in suitable bearings. The rearwheels of the wagon are traction wheels and have a pawl and ratchetconnection with their supporting shaft.

In the drawings, 1 is the supporting shaft for the traction wheels, 2 isaspur gear xed to the said shaft and engaging the spur pinion 8 which isloosely mounted on the outer end of the shaft 4.

5 is a sprocket wheel xed to the shaft 4, and the said sprocket wheel isconnected by means of the endless chain belt 6 with a similar sprocketwheel on the spreader cylinder shaft (not shown). The adjacent faces ofthe hubs of the spur pinion 3 and the sprocket wheel 5 are provided withengaging clutch teeth, as shown in Fig. 4. The sides of the pinion 3 areembraced by the two prongs 7 of a shifting lever 8 pivotally mounted ina bracket 9 on the side of the wagon body; by means of which shiftinglever the pinion 3 is moved into and out of clutch engagement with thesprocket wheel 5. The forward end of the shifting lever 8 is alsodivided, its ends 10`embracing the iange of the cam wing 11, said camwing being pivotally attached to the walls of the wagon box. The leverarm 12. of the cam wing is connected by means of the shifting rod 13,the crank arm 14 and the shaft 15 with the operating lever 16, which isfixed upon said shaft 15, and engaged by one end of a spring 16a coiledabout said shaft, the other end of said spring bearing against theforward end of the wagon body or any other fixed member, said springthus tending to throw said lever forward into a horizontal position. i

From the foregoing it will be seen that an upward movement of theoperating lever 16 turns the shaft 15, and through the shifting rod 13,rotates the vcam wing 11 and moves the shifting lever 8, throwing thepinion 3 into clutch with the sprocket wheel 5, which', by means of theendless chain belt 6,"rotates the spreader cylinder. The same turning ofthe shaft 15, acting through a crank-arm 15a and a connecting rod 17upon a sector 18, throws a worm 19 into engagement with a worm wheel 20,impartingmotion to the apron (not shown) of the spreader through amechanism new to be described.

To traverse the apron backward during the spreading operation, thefollowing described mechanism is provided. Upon a stub shaft 21 which issupported by a bearing bracket rigidly attached to the wagon body andnot shown in the drawings, isrotatably mounted a spur gear 22 meshingwith a similar gear 23. The inner face of said spur gear 22 is providedwith several rings of teeth 24 of differing diameters, the teeth ofwhich rings are adapted to mesh with a pinion 25 slidably mounted uponthe squared portion of a shaft 26, and having an upwardly-extending arm27 by means of which said pinion is moved longitudinally of its shaft.rlhe shaft 26 is rotatably mounted in two bearing brackets 23 and 29,the latter bracket being in sleeve form surrounding the stub shaft 21and having a bearing socket 30 for the forward end of said shaft 26. Thesleeve portion of said bracket 29 is provided on its upper side with twoears 31 forming between them a transverse groove adapted to receive anoscillatory cam wing 32 fixed with relation to the operating` arm 33.The opposite end of the shaft 26 carries a worm 19 fixed to said shaftand adapted to be moved into and out of engagement with the worm wheel20 by means of the sector 18 and the connecting rod 17. The worm wheel2O is fixed o-n the shaft 34, upon the other end of which is fixed asmall sprocket wheel 35 carrying the endless chain (not shown) whichmoves the apron of the spreader.

The speed of the apron travel with relation to the rotative speed of thecylinder may be changed by means of the apparatus now to be described.

A gear-shifting lever 36 pivotally attached to the side of t-he wagonbody at 36a is connected by means of the rod 37 with the arm 27 of thepinion 25. Pivotally attached to the upper or handle portion of the saidgear-shifting lever is a bell-crank lever 3S having its upper arm lyingadjacent to the handle of then lever 36 and its lower arm connected bymeans of the link 39 with the bell-crank lever 40, which is alsopivotally attached to the gear-shifting lever 36. The lower arm of thebell-crank lever 40 is connected by means of the rod 41 with theoperating arm 33 of the cam wing 32. A spring 43 is coiled about the rod41, one end engaging a stop fixed on the rod and the other end bearingagainst the stop 43a, which is fixed to the side of the wagon-body bymeans of the bracket 43h. lhen it is desired to change the speed of theapron, the operator grasps the handle of the lever 36, and in so doingpresses forward the upper arm of the lever 38, thus rotating the camwing 32 and throwing the pinion 25 out of engagement with one of thegear rings on the inner face of the spur gear 22. A movement of thelever 36 then moves the said pinion into coincidence with another one ofsaid circular rows of gear teeth. The lever 36 is movable within thelimits of a loop 42, and is slightly bent so as to press outwardlyagainst such loop. On the inner face of the loop 42 are grooves 42aadapted to engage the spur 42b and thus lock the lever at one of thevarious positions corresponding to the desired position of the pinion25. Then the said pinion has thus been locked in its proper position onthe shaft, the operator releases the handle of the lever and the saidpinion is again thrown into engagement with the corresponding ring ofgear teeth by means of the spring 43.

The appa atus herein shown may be changed in various ways withoutdeparting from the spirit and scope of our invention, wherefore wedesire to have it understood that we do not limit ourselves to thespecific construction herein shown and described.
